A tissue that consists of two generalized cell types, neurons and neuroglia. Neurons are specialized to initiate action potentials and conduct them at high speeds. Neuroglia provide numerous supportive functions.
Nervous tissue is the fourth major class of vertebrate tissue. The function of the nervous tissue is in communication between parts of the body. It is composed of neurons, which transmit impulses, and the neuroglia, which assist propagation of the nerve impulse as well as provide nutrients to the neuron.
